High Density Terminals (HD Terminals [
}
20]) with 16 terminal points
The conductors of the HD Terminals are connected without tools for single-wire conductors using the direct
plug-in technique, i.e. after stripping the wire is simply plugged into the terminal point. The cables are
released, as usual, using the contact release with the aid of a screwdriver. See the following table for the
suitable wire size width.

DANGER
Danger for persons, the environment or equipment
Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or
wiring of the Bus Terminals!
The supply connections V
k
for the module electronics (K-bus) and supply connections for the field devices
(power contacts) of a terminal block are galvanically separated from each other and can be supplied via
separate 24 V
DC
voltage sources. If no electrical isolation is required between K-bus and field devices, the
module electronics and the field devices can be supplied from a single voltage source.
NOTE
Notes on fail-safe operation
For the trouble-free operation of a K-bus extension system, the ground connection of the K-Bus power sup-
plies (Vk 0V) of all terminal blocks must be connected with each other via a low-resistance connection (see
Figure). This also includes the ground connection of the K-bus power supply of the higher-level Fieldbus
Coupler!
